Hi,
We have a stock answer about this that does get sent out to anyone who asks.
I am the one who sends them out and I am not seeing any unanswered emails about this. Perhaps it went to spam?
Here is the response:
Thank you for your email. We apologize for any confusion or inconvenience caused.
We are in the process of changing how we distribute our books on Kobo for sale.
As such, we are in a half-state/limbo state where some books are on the new method, and some are on the old method.Any books distributed on the new method will appear on the sale. Any on the old method will not.
We do plan on bringing all books from the old method to the new method in time. Unfortunately, that means some books part of our sale will not go on sale on Kobo.
